PrivCo provides intelligence on private companies, including financial estimates, ownership, contacts, funding and deal activity. Search filters include industry, location, revenue, EBITDA and ownership; users can save searches, create watchlists and monitor changes. Revenue, EBITDA and company-value estimates are presented with a range, update date, confidence level and supporting information. PrivCo says its main focus is U.S. private companies with annual revenue above $1 million, and that more than 85% of its coverage is bootstrapped or family-owned without outside VC or PE funding. The company describes combining licensed datasets, filings, court records, news, digital footprints and proprietary research, with automated checks and analyst review. Company information can be exported for outreach, internal review, market mapping and analysis. REST API and MCP access are documented, including connectors for Claude, ChatGPT and Microsoft Copilot; API access requires an enabled account. Free accounts provide AI-powered search but omit profiles, contacts, watchlists and exports. A seven-day List Builder trial has specified profile, search and contact-view limits and excludes exports and classic search tools.
